The BJ8 stock type exhaust hangs very low. The lower front edge of the two silencers under the driver's seat (LHD) can catch on speed bumps, high spots in the road, driveway slopes and so on. Hit something hard enough and you can actually damage the entire exhaust system. This heavy duty, 14-guage stainless steel skid plate will take the abuse that would otherwise damage the exhaust and will not rust.
